HUNTER'S MOON: There's a full Moon coming on Monday, Oct. 29th, and according to folklore it has a special name: the Hunter's Moon. Some native American tribes gave it that name to mark the autumn hunts that topped off their food supplies for the coming winter. Think of that when the bright orb rises tomorrow, and enjoy the Hunter's moonlight.

BE ALERT FOR MOON HALOS: The Moon is waxing full and the northern hemisphere is experiencing the deepening chill of autumn. That means it's time to be alert for Moon halos.

Moon halos are caused by ice in high clouds. Moonlight passing through six-sided crystals is bent into a luminous ring 22o in radius; the fuller the Moon, the brighter the halo.

The Moon will be nearly full on Oct. 28th and completely full on Oct. 29th, so those are good nights to look.

SLOW ERUPTION: The magnetic canopy of a sunspot group just over the sun's southwestern limb slowly erupted on Oct. 28th. When the hours-long eruption was over, this bright arcade formed over the blast site, marking the location where the explosion occurred:

Arcade loops appear after many solar flares. It is how the magnetic fields of sunspots settle down after a significant eruption. This particular eruption hurled a massive CME into space, but Earth was not in the line of fire. As the movie shows, the explosion was photogenic, but not geoeffective.www.spaceweather.com
